Researchers have discovered the most precise way to control individual ions using holographic optical engineering technology.

The new technology uses the first known holographic optical engineering device to control trapped ion qubits. This technology promises to help create more precise controls of qubits that will aid the development of quantum industry-specific hardware to further new quantum simulation experiments and potentially quantum error correction processes for trapped ion qubits.

“Our algorithm calculates the hologram’s profile and removes any aberrations from the light, which lets us develop a highly precise technique for programming ions,” says lead author Chung-You Shih, a Ph.D. student at the University of Waterloo’s Institute for Quantum Computing (IQC).

Now, in a world’s first, Daniel Robinson, a veteran F-22 pilot, climbed inside a real aircraft and battled an AI virtual fighter.

These virtual war games open up new doors for training in the U.S. military. Often, the only way to train airmen is with real pilots who oppose them in air-to-air combat training. The U.S. military is increasingly relying on contractors to provide “red air” adversary support. But physically flying against adversary aircraft pilots is costly and inefficient. Earlier this year, the Air Force hired several companies — in a multi-billion dollar contract — to get the support they needed to help pilots train across the U.S.

Neodymium is critical to making the wheels of a Tesla spin or creating sound in Apple’s Airpods, and China dominates the mining and processing of this rare-earth mineral. So the U.S. and its allies are building their own supply chain. Photo illustration: Clément Bürge/WSJ

NASA’s Parker Solar Probe just took its closest pass to the Sun yet, veering so close that it “touched” the star’s blisteringly hot outer atmosphere — and gave NASA an unprecedented firsthand look at it.

The car-sized spacecraft has zoomed past the Sun a few times now, veering closer and closer each time, according to CNET. Each time, it uses nearby Venus’ gravitational pull as a sort of slingshot that helps it travel closer to the Sun and propels it at higher and higher speeds each time.

The slingshot is working so well that the space probe broke two records during its most recent solar approach last week.

The intractable “three-body problem” gets closer to being solved with breakthrough study.

The thumbnail-size amphibian lives in Brazil’s Atlantic Forest, which has lost 93 percent of its forest cover.

Mastering meat production in this way will lead to advances in medical science and treatment.

“Cultured meat also ultimately offers the opportunity to create meat products that are more well-defined, tunable, and potentially healthier than meat products today, which are constrained by the biological limitations of the domestic animals from which they are derived.”

Owing to advances in industrial-scale cell culture process, the production of cultured meat has been largely standardized. Typically stem cells are first seeded into extracellular matrix scaffolds usually made of edible biomaterials like collagen and chitin. To support cellular metabolic activities, culture media containing nutrients like glucose and sera are next added to the bioreactor where continual mechanical motion facilitates good diffusion of nutrients and oxygen into and removal of metabolic waste products from the cells. After about 2–8 weeks, the cells grow into tissue layers and can be harvested and packaged.

In work that could someday turn cell phones into sensors capable of detecting viruses and other minuscule objects, MIT researchers have built a powerful nanoscale flashlight on a chip.

Their approach to designing the tiny light beam on a chip could also be used to create a variety of other nano flashlights with different beam characteristics for different applications. Think of a wide spotlight versus a beam of light focused on a single point.

For many decades, scientists have used light to identify a material by observing how that light interacts with the material. They do so by essentially shining a beam of light on the material, then analyzing that light after it passes through the material. Because all materials interact with light differently, an analysis of the light that passes through the material provides a kind of “fingerprint” for that material. Imagine doing this for several colors — i.e., several wavelengths of light — and capturing the interaction of light with the material for each color. That would lead to a fingerprint that is even more detailed.
